【To all users】

  • The cold cathode crookes tube with a maltese cross can demonstrate linearity in emitted electrons.
  • The cold cathode crookes tube with deflection plates can demonstrate that the emitting electron beam can be bent by electric field.

【To teachers】

  • Moving of the cathode rays in straight line is observed by the rays casting a shadow of cross shape on the back face of the tube.
  • The effect of electric field on the electron beam in the tube is observed by using the tube with deflection plates and a magnet.
